Description
TECHNICAL FIELD
The present invention relates to devices for packaging and applying
a product, especially a cosmetic product, for example mascara or a
lip gloss, comprising a container containing the product to be
applied and an applicator comprising an application member at the
end of a wand. A wiping member is borne by the container in order
to wipe the wand of the applicator and the application member when
the latter is removed from the container.
BACKGROUND
Many wiping members have already been proposed, in order to adapt
the wiping as best possible to the nature of the application member
and/or to the shape of the wand. Indeed, it may be desirable not to
wipe the application member too vigourously as it is liable to
reduce the autonomy of the applicator and/or render makeup
application more difficult.
U.S. Pat. No. 7,476,004 describes a wiping member comprising a
tubular mounting skirt in contact with a wall of the container and
a tubular-shaped wiping lip that extends axially beyond the
mounting skirt towards the bottom of the container. This skirt is
made with recesses so as to orient particles contained in the
product, such as glitter, during passage of the wiping member. The
application member is borne by a wand having a rectilinear
longitudinal axis.
FR 2826246 discloses a wiping member comprising a conical-shaped
wiping lip and a tubular part that extends the mounting skirt
underneath the wiping lip and around the latter. The lower end of
the wiping member is defined by this tubular part.
U.S. Pat. No. 5,490,737 describes a wiping member comprising a
flocked wiping lip that extends the mounting skirt. The application
member is borne by a wand having a rectilinear longitudinal
axis.
US 2012/026355 discloses a wiping member provided with a flexible
wiping lip bearing spikes on its outer surface. The application
member is borne by a wand having a rectilinear longitudinal
axis.
DE 196 42 720 A1 discloses a wiping member comprising a wiping lip.
Only one edge of the wiping lip comes into contact with the
application member during wiping.
There is a need to further perfect the wiping members and in
particular to have a wiping member capable of satisfactorily wiping
an applicator despite a complex geometry of the application member
and/or of the wand, for example the presence of a wand having a
non-rectilinear longitudinal axis.
SUMMARY
The invention meets this need by virtue of a device for packaging
and applying a product, especially a cosmetic product, comprising a
container containing the product and an applicator comprising a
wand, provided at one end with an application member, the assembly
formed by the wand and the application member having a
non-rectilinear longitudinal axis, and a wiping member borne by the
container in order to wipe the wand and the application member when
the latter is removed from the container, the wiping member
comprising a tubular mounting skirt in contact with a wall of the
container and a tubular-shaped wiping lip having a length greater
than or equal to its internal diameter, extending axially beyond
the mounting skirt towards the bottom of the container.
The wand may have a non-rectilinear longitudinal axis.
As a variant, or additionally, the application member is bent
relative to the wand and/or has a curved longitudinal axis.
The wiping lip, due to its tubular shape and its length, is capable
of wiping a non-rectilinear wand more effectively.
The wiping thus advantageously takes place along the tubular
portion, the latter preferably being adapted to come into contact,
over substantially all of its length, with the wand. Thus, the
tubular portion of the wiping lip may have an internal diameter
which preferably departs little from a nominal value that
corresponds substantially, preferably, to the diameter of the
wand.
Preferably, the wiping lip is connected to the mounting skirt by a
narrowed intermediate part.
The presence of the narrowed part gives increased flexibility to
the wiping member and enables it to more easily take on the
orientation necessary for the passage of the wand and/or of the
application member.
Preferably, the container is made in a conventional manner, that is
to say that it comprises a neck in which the mounting skirt is
engaged, the latter preferably being snap-fastened to the neck. The
wiping member may comprise a flange for attachment to the
container, in particular underneath a shoulder of the container at
the base of the neck.
The product contained in the container may be mascara, containing
for example an iron oxide.
The mounting skirt may be narrowed over a portion of its length
above the attachment flange, in particular due to the presence of
an annular groove formed on the radially outer surface of the
mounting skirt.
The narrowed part may be delimited on the outer side by an annular
groove. The narrowed part may have a minimum thickness of between
0.4 mm and 1 mm.
The wiping member may have a shoulder at the base of the mounting
skirt, on the inner surface thereof.
The wiping lip is preferably continuous over its entire height.
The wiping lip is preferably unchamfered at its lower end.
Preferably, the wiping lip has a circular internal cross section.
As a variant, the wiping lip has a non-circular internal cross
section. In this case, the internal diameter D.sub.int of the
wiping lip should be understood to mean the diameter of the largest
circle inscribed in its smallest internal cross section.
Preferably, the internal diameter of the wiping lip is
substantially constant over a distance at least equal to D.sub.int,
better still double or even triple D.sub.int. The expression
"substantially constant" should be understood to mean that the
internal diameter is equal to D.sub.int to within 10%, that is to
say is between D.sub.int and 1.1 D.sub.int.
The smallest internal diameter D.sub.int may be the diameter at the
lower end of the wiping lip.
The lower end of the wiping lip preferably also defines the lower
end of the wiping member.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
The packaging and application device 1 shown in FIG. 1 comprises a
container 10 intended to receive an applicator 20 as illustrated in
FIG. 5, that may be attached to the container when not in use.
The container 10 comprises a body 11 surmounted by a neck 12 to
which a wiping member 30 in accordance with the invention is
attached.
A product is contained in the container, preferably a cosmetic
product to be applied to the eyelashes and/or the eyebrows,
especially mascara, or a product to be applied to the lips.
The applicator 20 comprises a wand 21 provided at one end with an
applicator member 22 and at the other end with a gripping member 23
that likewise forms a cap for closing the container.
The neck 12 may be threaded and the gripping member 23 may be
attached to the neck 12 by screwing.
The application member 22 may be of any type, for example being a
mascara brush produced by injection moulding of plastic, or a brush
having a twisted metal core.
The wand 21 may have a non-rectilinear longitudinal axis X, in
particular that extends in the three spatial directions.
In particular, as illustrated, the wand 21 may have at least two
bends about non-coplanar axes.
The wand 21 may be produced from an elastomeric material, so as to
be able to deform during extraction from the container, for example
from a thermoplastic elastomer.
The angle between the respective longitudinal axes Y and Z of the
gripping part 23 and of the application member 22 may be greater
than or equal to 25.degree..
The radii of curvature of the two bends may be different, it being
possible for the radius of curvature of the first bend, closer to
the gripping member 23, to be greater than that of the second
bend.
If reference is more particularly made to FIGS. 2 and 3, it is seen
that the wiping member 30 comprises a mounting skirt 31, which is
attached to the neck 12 of the container 10, which is terminated at
its upper end by a flange 32 which bears against the edge of the
upper end of the neck 12.
The wiping member 30 comprises an attachment flange 33 which is
connected to the base of the mounting skirt 31 and which bears
against a shoulder 15 formed at the base of the neck 12 by the body
11 of the container.
The flange 33 has at rest, before mounting of the wiping member in
the container, a lower face 32a of substantially conical shape. A
bead 34 is present on the opposite face, over its outer perimeter,
being intended to bear against the container.
The mounting skirt 31 may also have, as seen in particular in FIG.
3, an annular bead 35 slightly forming a projection over its
radially outer surface 36.
An annular groove 37 may be present above the flange 33 on the
surface 36. This groove facilitates the mounting of the wiping
member, by enabling the flange 33 to be pushed back against the
mounting skirt.
The internal diameter Dj of the mounting skirt 31 may be
substantially constant, at least over a length Lj, and between for
example 7.3 and 7.6 mm.
The wiping member 30 may have a chamfer 38 at the end flange
32.
The wiping member 30 may have a shoulder 39 at the base of the
mounting skirt 31, on the inner surface thereof. The shoulder 39 is
useful for the mounting, by bearing on top of it in order to push
the wiping member 30 into the neck of the container.
The radially inner edge 60 of the shoulder 39 has a diameter De
between 6.5 and 6.7 mm for example.
The mounting skirt 31 is extended below the shoulder 39 by a wiping
lip 70 which comprises a tubular part 71 that is connected to the
mounting skirt by a narrowed intermediate part 72.
It is shown on FIG. 4 that the narrowing of the intermediate part
72 is linked to the presence of a groove 74, opened in the
direction of the bottom of the container.
The inner surface 76 of the intermediate part 72 comprises a
conical portion that converges in the direction of the bottom of
the container, and which is connected by a rounded portion 78 to
the inner surface 79, substantially in the form of a cylinder of
revolution about the longitudinal axis W of the tubular portion
71.
The radius of curvature R1 of the rounded portion 78 is for example
between 0.5 and 3 mm.
The radius of curvature R2 of the groove 74 at its ends is for
example between 0.2 and 1 mm.
The radius of curvature R3 by which the conical portion 76 is
connected to the side 80 below the shoulder 39 is for example equal
to the radius of curvature R2, being for example between 0.2 and 3
mm.
The length O between the lower end 81 of the mounting skirt 31 and
the lower end 82 of the tubular portion 70 is for example between 6
and 13 mm and in particular equal to 11 mm or to 8 mm.
The wiping lip may have, along the tubular portion 71, an internal
diameter D.sub.int that is substantially constant, in particular
between 2.5 mm and 6 mm, better still 3.7 mm and 3.9 mm, for
example equal to 3.8 mm.
Preferably, the wiping lip 70 has a length k greater than the
internal diameter D.sub.int. The wiping lip 70 preferably has a
length k greater than or equal to 6 mm, better still 7 mm.
The radially outer surface 83 of the wiping lip may be located
radially set back from the inner surface of the mounting skirt, in
particular above the shoulder 39 present at the base of the
mounting skirt.
The wiping member 30 may be made from a thermoplastic material, in
particular from NBR or nitrile rubber. The wiping member 30 may be
moulded in one piece from thermoplastic material.
In order to manufacture the device 1, the wiping member 30 is
forcibly inserted into the neck 12 of the container.
When the applicator 20 is removed from the container, the
application member 22 crosses the tubular portion 70. The narrowed
intermediate part 72 may enable the tubular portion 72 to deform
more easily. This deformation may be radial and/or correspond to an
inclination of the axis of the tubular portion 70 with respect to
the longitudinal axis W of the wiping member at rest.
The wand 21 may also be appropriately wiped, having a diameter
substantially equal to or slightly smaller than the internal
diameter D.sub.int of the wiping lip 70.
The invention is not limited to the examples that have just been
described. For example, it is possible to modify the length of the
tubular portion or the way in which the wiping member is attached
to the container. It is also possible to give other shapes to the
wand of the applicator, in particular to modify the number of
bends, the position thereof, and the radii of curvature.
The expression "comprising a" is synonymous with "comprising at
least one".
